arduino + mpu6050 无法输出数据的问题

3837 MPU6050

问答对人有帮助，内容完整，我也想知道答案 0 正确接线，打开串口监视器却不见有数据输出。初步怀疑: 1.如图，直接插在面包板上，我怀疑接触不良 2.这个模块上面有一个电容和三极管的一个引脚焊在一起了，但正常它们不会出现碰线这种情况，如图淘宝商家给的代码如下（见附件 MPU6050_raw.zip (43.58 KB, 下载次数: 7 ) ） // I2C device class (I2Cdev) demonstration Arduino sketch for MPU6050 class // 10/7/2011 by Jeff Rowberg <jeff@rowberg.net> // Updates should (hopefully) always be available at https://github.com/jrowberg/i2cdevlib // // Changelog: // 2011-10-07 - initial release /* ============================================ I2Cdev device library code is placed under the MIT license Copyright (c) 2011 Jeff Rowberg Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
